The answer is 1/7 and can be explained mathematically in the picture
Answer:$21.20
Step-by-step explanation:
5.30x and x =4
5.30 times 4 is 21.20
David reads 80 pages every day.
Karen reads 25% more pages every day than David reads.
So, Karen reads more pages. She reads a total of 80 + 20 =100 pages.
Rick reads 35% fewer pages per day than Karen. So, Rick reads less pages than Karen. He reads 100 - 35 =65 pages
So, in total the tree friends read = 80+100+65=245 pages.
So, equation becomes
Answer:
2 - x^2
Step-by-step explanation:
The nearest tenth of how fast a rover will hit Mars' surface after a bounce of 15 ft in height is 20.7ft/s.
<h3>What is the approximation about?</h3>
From the question:
Mars: F(x) = 2/3
Therefore, If x = 15
Then:
f (15) = 2/3
= 16/3
= 20.7ft/s
Hence, The nearest tenth of how fast a rover will hit Mars' surface after a bounce of 15 ft in height is 20.7ft/s.
